Hello, We are using tinc 1.0.24 with switch mode. Some questions regarding to the UDP connections on tinc.
As far as I understand tinc is building meta connections with "ConnectTo", and "ADD_EDGE" packet. With the help of EDGE info two nodes who don't have direct meta connection are able to communicate through direct UDP connection. I understand we can dump the meta connection using USR2 signal. However is there a way to know if a direct UDP connection exists between two nodes? UDP connection will fall back to the meta connection(with next-hop..) if the direct UDP fails, but what are the possible reasons for its failure? Currently we have a connection like below: A-->H G-->H D-->A E-->A F-->A If we try to send packets directly from G to D, seems the direct UDP connection always fails and it is going to path G-->H-->A-->D, however somehow it got broadcasted during the process, because I can see that message on E and F. Does this even make sense? Any suggestion will be appreciated. Thank you.
